Just Upgraded to MCUXpresso 11.4.0 and Error loading in .mex file

[myke_predko]

Hey NXPers,

I just upgraded to MCUXpresso 11.4.0 on Linux and when I try to load a project or use the Wizards, I get the pop up:

Error during opening configuration <ProjectName>/mex:

Communications error.  Check the connectivity to the Internet and repeat again.  

I'm not sure what this means as clearly the Internet connection is fine (or you wouldn't be seeing this).  It's the same for all projects and .mex files.  

I've reverted back to 11.3.1 and things seem to be working fine there.

Comments?

I'm also sharing this with the MCUXpresso forum.

Hi Myke:

I just installed MCUXpresso 11.4.0 (not upgraded from 11.3.1) on Ubuntu 20.04 and imported a hello world demo, compiled successfully.  not found the error you mentioned.  I would suggest you try it again. update your results on MCUXpresso IDE forum.

Regards

Daniel

I downloaded MCUXpresso 11.4.0 again and it seems to work (although it's not flawless).  

My comments regarding the build are in the MCUXpresso IDE forum.

Hi @danielchen 

Did the project have a .mex file?
